Re: [PyMOL] How to manually define the lower and upper limit of vacuum electrostatics?

[sunyeping <sun...@al...>]

Hello, Marko,

Think you for your reply. I can use the bar object "Action" > "Levels" to set the levels/scales to -100~100, but could you tell me what are the units for the values?

Best regards

 Hi Yeping, 

 Click on the bar object "Action" > "Levels" for a few preset levels/scales.

Dear all,

I am trying to compare the vacuum electrostatics of three related proteins. I loaded them in pymol and use "Action>generate>vacuum electrostatics menu to generate the vacuum electrostatics of the three proteins. I find that the lower and upper limit of the gradient bars generated with the  vacuum electrostatics of the three proteins are different. They are -64.1~64.1, -72.2~72.2 and -82.2~82.2, respectively.  

I wonder whether I could define the lower and upper limit of the gradients to the same values so that the vacuum electrostatics of the three proteins can be better compared?

Best regards.
